Question about 2002 Mercury Sable
Door alarm comes on while driving. I get into the car, and the door alarm continues several times with the interior lights on. It stops but then comes on several times while driving. No doors are open. . Also, after locking doors the car alarm has gone off.
This is caused by a defective door ajar switch in one of the 4 doors. The switch is located on the back of the door latch mechanism inside the door. The system can be tested to id the defective switch which is far better than just removing all 4 door panels and rear glass channels to access the 4 switches. Each switch is about $15.00 time to remove them about 4-5 hours for all doors to do this the hard way.

There is a small switch inside the door area, and it is obviously broken. The switch is usually held in place by 1 screw, and has a wire clip attached to the interior side. If you replace that switch. your issue should cease.
Simply remove the screw that retains that switch, pull it out of the body, remove the wire clip. and install the new switch in reverse.
I hope this information helps you, and I wish you luck on your repair.

There are 2 things we see on these models. 1st one is it could be a stuck door adjar switch. For this you can try and put WD40 into the latch on the side of the door, put a generous amount directly into the latch then close and open the door several times.This will un-stick a switch most of the time.
2nd thing it could be, open the door and look at the front of the opening between door and A pillar and you will see a black rubber accordian tube running between body and door,this is where the wires run from body to door. Sometimes a wire will break inside this.You can usually verify this by taking a screwdiver and trip the latch so that it shows the door closed(even though u have it open) then wiggle that harness and see if it effects the door adjar light.

I had the same problem in my 98 and 96 Sables. Ford dealer says it is a problem with a sensor, located behind the left rear quarter panel. It doesn't recognize when the doors are closed, therefore it leaves the dome light, etc. on--sometimes briefly, but possibly until the battery goes dead. Worse when the weather is damp. Their solution was to throw it on the diagnostic computer BUT ONLY WHILE THE PROBLEM IS ACTIVELY HAPPENING, then replace the sensor--they quoted me a minimum of $300. I leave the cover off the dome light, and pull the bulb when necessary.

you will need to check the door harnesses. the wires crack over time due to the opening and closing of the doors.
check them for broken wires.
